Has anyone edited the blender source code to enable unlimited undo's?
The Undo feature in the blender works by storing a copy of the file inside computer memory for every single thing you do. It means that you really can't have infinite undo steps availible. However, you can increase it to a very high number.
Goto Edit-&gt;Preferences-&gt;System, and then change the value in &quot;Undo Steps&quot; under &quot;Memory and Limits&quot;.
